Serial No. 304,785.

To all whom it may concern:

Be it known that I, GEORGE EUGENE BAR- RETT, a citizen of the UnitedStates, residing at Duluth, in the county of St. Louis and State ofMinnesota, have invented new and useful Improvements in Cultivators, ofwhich the following is a specification.

This invention relates to cultivators, the object of the invention beingto provide a shield embodying separate and independently-adjustablesections or members, the shield as a whole being adjustable up and downto suit plants of different sizes and also being adapted to protectyoung and tender plants from being injured by the soil thrown up by theshovels of the cultivator and at the same time provide for a thoroughand effective cultivation of the plants.

A further object of the invention is to make the shield as a wholeadjustable in height, so that the shield may be raised as the plantsincrease in size.

A further object of the invention is to provide a novel form of shieldmember especially adapted for use in connection with plants havingspreading leaves which lie close to or upon the ground, whereby theleaves are raised to allow the soil to be thrown close up to the stalksof the plants and beneath the leaves thereof without danger of injuringthe plants.

IVith the above and other objects in view, the nature of which will morefully appear as the description roceeds, the invention consists in thenove construction, combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a plan view of a cultivatorembodying the present invention, being shown partly in section. Fig. 2is a cross-sectional view thereof on the line 2 2 of Fig. 1. Fig.3 is adetail elevation of one of the hangers. Fig. 4 is a detail perspectiveview of one of the shield members. Fig. 5 is a plan view similar to Fig.1, showing modified means for supporting and adjusting the shield. Fig.6 is a cross-section on the line 6 6 of Fig. 5. Fig.7 is an enlargeddetail vertical section showing the relation between one of the shieldmembers, a hanger, and the arm which connects the shield to the hanger.Fig.8 is a side elevation of the hanger and shield-supporting arm orcarrier. Fig. 9 is an enlarged cross- 12 is a sectional elevation of thesame.

section through the arrangement shown in Figs. 6 and 8. Fig. 10 is adetail elevation of one of the adjusting-blocks for the shieldcarrierarms, showing also a portion of one of the arms. Fig. 11 is a plan viewof the cultivator, showing a modified arrangement of carrier andadjusting means therefor.

1g. 13 is a sectional plan view of one of the guides or sockets.

Referring to the drawings, 1 designates the main axle, provided with thecarrying-wheels 2 and connected with the pole or tongue 3, while 4designates a pair of beams connected to the axle 1 and extendingrearwardly therefrom in parallel relation to each other.

In carrying out the present invention each of the beams 4 is preferablybifurcated to form substantially parallel branches 5, each of which isextended downward to form a standard 6, to the lower end of which isconne'cted a shovel 7. Any desired number of shovels 7 may be provided.

Under the arrangement shown in Fig. 1 a vertically-disposed hanger 8 isconnected to the inner side of each beam 4, said hanger consisting of abar provided with a grooved seat 9, in which the beam 4 is received,said parts being firmly connectedby a bolt 10 or its equivalent- Thelower eno of the hanger 8 is slotted longitudinally, as shown at 11, andalso has its inner face toothed or serrated, as shown. at 12, said slotand toothed face providing for the adjustment up and down thereon of aflanged block 12, to which is pivotally connected a shield-member arm orcarrier 13. The block 12 is secured to the serrated face 12 of thehanger and is itself serrated or toothed to engage therewith, as shownat 14. A fasteningscrew 15 extends through the slot in the hanger 11 andengages the block 12 as shown in Fig. 2, thus providing for adjustingthe block and carrier 13 up and down-on the hanger to raise and lowerthe shield member carried thereby. The block 12 is provided with flangesor inclined shoulders 12 which allow the carrier 13 to tilt u ward, butprevent it from falling below a iorizontal position.

The carriers 13 are offset inwardly, as shown in Fig. 1, and the rearend portions thereof are extended backwardsubstantiallj; parallel toeach other and provided wit sockets 16, in which are received theforwardly-extending shanks 17 of the shield members, said shanks beingsecured in place by means of binding-screws 18, which permit the shanks17 to be adjusted fore and aft and also to be turned on theirlongitudinal axes for adjusting the angles of the shield members, aswill be readily understood by an inspection of Figs. 1. and 2.

The shield is composed of two members 19, which may be termed shieldplates or boards, the said shield members being adapted to be normallydisposed at an angle to each other like an inverted V, as best illustrated in Fig. 2, with their upper edges touching or in close proximityto eachother, their lower edges moving in close proximity to or inactual contact with the surface of the ground. 1

-Under the arrangement shown in Figs. 1 and 2 the shield members 19 areconnected rigidly to the shanks 17, While said shanks are adjustableboth fore and aft and axially within the socketed rear ends of thecarriers 13. This provides for adjusting the shield members 19 to anydesired angle necessary to properly cover and protect the plants duringthe progress of the machine across the field. 1t will also be seen thateach shield member is adjustable independently of the other and thatboth of the shield members are adjustable up and down to accommodatethem to the plants as they increase in size. The V-shaped relation ofthe shield members provides for dividing the soil thrown by the shovelsand forms a com plete shade over the plants, causing the soil to fallclear of the plants without danger of the same passing backward over therear end of the shield and falling upon the plants to the injury of thelatter.

Where the plants have spreading leaves lying upon the ground, I employ aspecial form of shield 19, as shown in Fig. 4, the lower portion of saidshield being bent inward'to form an inwardly-extending flange 20, whichis adapted to ride beneath the outspreading leaves of the plants,picking them. up and allowing the loose soil displaced by the shovels tocrowd inward beneath the leaves and up close to the stalks of theplants.

In Figs. 5 to 9, inclusive, I have illustrated a slight modification inthe manner of mounting the shield members, involving, however, the sameprinci 1e. In said figures it will be seen that the s ield members 19are pivotally connected at 20 to the carriers 21 which under saidmodified arrangement are in. the form of upstanding arms or slides,which overlap and slide upon the depending portions 22 of the hangers.Each of said hangers is extended laterally, as shown at 23, and thenoffset downwardly, as at 24, and then extended laterally outward to forma shank 25,.which extends across the top edges of the longitudinally, asshown at 29, and binding screws 30 pass through said slots and engagethe carriers 21, so as to provide for adjusting said carriers up anddown and correspond ingly raising and lowering the shield members 19.

From the foregoing description it will be seen that the shield members19 may be adjusted independently upward and downward on the hangers andthat the hangers may be adjusted fore and aft on the branches 5 of thebeams or adjusted laterally with respect to said beams so as to providethe necessary distance between the shield members.

By reason of the connection between the arms 14 and the adjustableblocks 12 the shields are adapted to automatically rise and fall whenpassing over obstructions, while at the same time the arms are preventedfrom falling below a substantially horizontal position.

Under the arrangement shown in Figs. 11, 12, and 13 each of the carriers(indicated at 31) is made in one-piece with the hanger, the carrier 31having the forward end portion thereof bent upward to extend verticallythrough a bearing or socket 32, secured to the machine -frame andprovided with a binding-screw 33, by means of which the vertical portion34 of the carrier may be held at any desired adjustment. The rear end ofeach carrier is bent to extend hori-' zontally, as shown at 35, where itpasses through guides or sockets 36, secured to the outer face of one ofthe shield members 19, and one of said guides or sockets is rovided witha set-screw 37, which enables t e shield member 19 to be adjusted backand forth on the horizontal portion 35 of the carrier and to be fastenedwhen brought to the desired position. By the means just described theshield members may be adjusted back and forth and also up and down tobring the same in the desired relation to the plants and to the plows orshovels, so that said shield members will efiectually protect the lantsas the machine is drawn along the eld.

I claim- 1. The combination with a cultivator, of'

- ward and away from each other in a direc- The portions 22 of the hangtion transverse to the path of movement of the cultivator to vary thedistance between the shield members.

' 2. The combination with a cultivator, of a plant-shield comprisingangularly-disposed members adjustable relatively to each other and eachhaving an inwardly-extendin flange at the bottom thereof, substantiallyas described.

3. The combination with a cultivator, of a plant-shield embodyingangularly-dis osed members provided with shanks, and s 'eldcarriersconnected with the machine-frame and provided with sockets to receivethe shanks of the shield members, said shanks being adjustably connectedwith the carriers.

4. .The combination with a .cultivator, of a plant-shield embodyingangularly-disposed members having shanks, and shield-carriers adjustablyconnected to the machine-frame and provided with sockets in which saidshanks are received, and means for adjusting said shanks to vary therelative angles of the shield members.

5. The combination with a cultivator, of

a plant-shield embodying angularly-disposed members, hangers thereforconnected to the cultivator-beams, blocks adjustable up and down on saidhangers and provided with flanges having inclined shoulderssubstantially parallel to each other, and carriers for said shieldmembers pivotally connected to said blocks and interposed between theshoulders thereof.

6. The combination with a cultivator, of a plant-shield embodyingangularly-disposed members, upright hangers therefor connected to thecultivator-beams and having serrated inner surfaces, serrated blocksadjustable up and down on said hangers, and carriers for said shieldmembers connected to said blocks and adjustable up and down therewith onthe hangers.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE EUGENE BARRETT.
